A few more thoughts:
The Obi-Wan missed jump looks too off to me. (The first one, not the overshoot, which is still awesome) To me, it doesn't look like he jumps and misses, which I think is your intention, but just that the footage is reversed. I say either play with that one a little more or go right to the overshoot.
And as far as the "simple flip leaves continuity errors"... What errors? Is it anything worth worrying about? This is a ridiculous edit, afterall.
